SPECIFICATION forming part of Letters Patent No. 299,217, dated May 27,1884. Application filed February 16, I884. (No model.)

To ctZZ whom it may concern:

Be, it known that I, Gnonen E. GORHAM, of Albany, in the county ofAlbany and State of New York, have invented certain new and usefulImprovements in Friction Devices for WVindow-Sashes; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My improvement relates to means for in ducing frictional contact betweenthe upper and lower sashes of a window, to cause them, when closed, tobe in such close proximity as to prevent the ingress of air fromwithout, thus dispensing with the use of listing, and also effectuallypreventing rattling of the sashes at whatever position they may bebrought.

To these ends the invention consists in the attachment to the sash andframe of such de vices as will be hereinafter distinctly described, andpointed out in the claims.

Reference being bad to the annexed drawings, Figure 1 represents anouter vertical elevation of the two sashes, embodying in connectiontherewith the employment of my im- Fig. 2 is a vertical sectional viewthereof on the line 3 y." Figs. 3 and 4 are inner and outer verticalelevations, respect ively, of a window sash and frame, in which is shownthe employment of a substantial modification of the devices shown in'the preceding figures. Fig. 5 is an enlarged view in perspective of themodification, showing a portion of the window-sash.

Referring to the several parts by letter, and in connection with Figs. 1and 2 of the drawings, A represents the upper sash, having attached tothe outer face of the stiles the main portion of my improved device.

13 represents the lower sash, against which the said upper sash iscaused to be pressed by the action of the device.

C designates the window-frame, in which the sashes move.

The devices for producing sufficient frictional contact between thesashes for acoomplishment of the above-described objects consist ofspring-strips a, which are preferably secured to the outside of thestiles of the upper sash and the inside of the stiles of the lower one,in such manner as to bring a bulging end near or on a line with thelower beveled cross-piece of the upper sash and the upper beveledcross-piece of the lower oneor, in other words, the points of junctureof the two sashes when closed-4n order that the required pressure willalways be maintained at this point.

It will be observed that the springs are bulged outward at each end,which produces a depression or concave in the direction of their length.While in this shape they are tempered to give them the proper tensionand resilient effect.

Projecting outward from the frame across the face of the stiles arepins, 2), which may be provided with loose] y-turnin g rollers, as shownin Figs. 1 and 2; but I prefer simply employing pins. These are arrangedon the frame in two series, (the one for the upper sash being without,while the one for the lower sash is within,) so as to permit the bulgesof the springs to be engaged therewith at varying heights, and one ofthe series on the outside and one of the inner series are located at a jpoint beneath and just past the lower bulge of the upper spring and theupper bulge of the lower spring, respectively, against which they bear,and as a result the beveled portions of the sashes are firmly pressedtogether. In addition to a force being exerted in a direct linetransverse to the sashes, these lower and upper rollers of the series,by virtue of their location with respect to the springs, tend to exertforces perpendicular to the first, and thus is the support of the uppersash aided, and the counterpart or correspondingly-beveled cross-piecesof the sashes made to tightly abut.

In Figs. 3 and 4 I have shown a wire spring for accomplishment of theabove ends, which is provided at about the center of its length with asemicircular bend, f, and at a suitable distance from each side of suchbend their ends branch off at an acute angle. Thus is given a bulge ateach angle where the ends branch, the same as in the above-describedinstance. When this spring is secured to the sash-stiles, I propose todrive in a small staple, 5/, over the semicircular bend, until thespring is slightly depressed or drawn in toward the it to allow ayielding action and at the sametime to prevent lateral bending. Thiswire spring is of substantially the same generic shape as the flatspring first described. My reason for forming it with the semicircularbend and employing a staple in connection therewith is that, by sodoing, I obtain a sufficient tension without having to temper it afterits formation, as is frequently necessary in the first form. The springsare preferably secured to the outside of the stiles of the upper sashand the inside of the stiles,of the lower one. Two ormore can be used oneach stileone above the other-in which case the number of pins on theframe would be less; or by increasing the number of pins 3. singlespring on each stile will be found sufficient.

.From the above it will be seen that thesashes can be brought to anypoint for the purpose of ventilation, the devices always maintainingtheir efficacy as anti-rattlers by pressing the sashes against theparting-strips, while the sashes, when closed, are firmly pressedtogether, thus dispensing with the employment of listing.

The sashes can be opened to the desired extent and allowed to rest onsome one of the pins, which will prevent their falling.

1 Having thus described my invention, what I claim, and desire to secureby Letters Patrnt, .1s

1. In devices for producing frictionbetween the meeting-railsofwindow-sashes when closed and between the parting-strips and sasheswhen open, the combination of the springs a, having upper and lowerbulges, and secured at their outer ends to the stiles, as described, andpins extending from the frame across the springs, against which thebulges bear, substantially as and for the purpose set forth.

2. The combination, with the sashes and frame of a window, of the springsecured at its outer ends to the sash, and having upper and lowerbulges, and formed with the semicircular bend f, the staple g, and pinsextending from the sides of the frame against which the bulges of thespring bear, substantially as and in the manner described.

In testimony that I claim the foregoing as my own I affiX my signaturein presence of two witnesses.
